BRUSH.

Application `led June 14,

T0 @ZZ-'whom 'it may concern:

Be it known that I, ANTHONY P. BREN- NER, acitize-n. of the United States, and a resident of the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

The present invention relates to improvements in brushes and their construction, and more particularly to those intended for calcimining, stuccoing, and kindred purposes.

A principal object of the invention is to provide a brush of the character specified that shall be comprised of units of simple and cheap construction, readily assembled, and that shall, when fully completed, be efficiently reenforced and so constituted as to retain the bristle-body in proper and permanentposition.

A further obj ect of the invention is to provide a bristle-retaining member of substantially frustum shape and one-piece construction, comprising a plate having a handleaperture and carrying reenforcing elements adapted to strengthen both handle-aperture and plate, and supplied interiorly with partitioning means for dividing and assisting in securing and locking in position an extremity of the bristle-body.

With these and other objects that will appear later, and be more fully set forth in the claims appended hereto, the invention consists of the parts and the construction, combination and arrangements shown in the accompanying drawings, forming a part of this specification, and in which similar characters of reference refer to like parts, throughout.

Figure 1 is a side elevation, showing the brush in that form best adapted to calcimining; Figure 2 is an elevation showing a different view of same type of brush as shown in Figure 1; Figure 3 isfa side elevation of the type of brush adapted for stucco work; Figure 4 is an elevation of same type shown in Figure 3 but of different view; Figure 5 is a transverse-section of the bristleretaining member of the type adapted for calcimining, showing its frustum form, the partitioning means and reenforcing elements, and Figure 6 is a transverse-section of the bristle-retaining member of the type of brush adapted for stucco work, showing its frustum form, together with handle-recess, bristle-partitioning means, bristle-re- 1923.

member to itshandle.

Referring more particularly to the drawings, 1 represents the bristle-body vportion of the brush, 2 the plate containing an aperture 3 and provided with a brush head holder 4, 5 a reenforcing bead surrounding aperture 3, 6 a reenforcing flange borne by aperture 3, 7 a reenforcing bead on the brush head holder 4, 8 a reenforcing ferrule having an aperture 9 and litted to seat within the bead 5 borne by the plate 2, 11 the handle, beaver-tailed as to shape, shouldered as at 12 to rest upon the surface adjacent the aperture 9 and having a reduced eXtremity 13 fitting into the apertures 3 and 9, 14 longitudinally arranged partitional means, and 15 a screw for securing the plate 2, together with its attached elements, to the handle 11.

Aside from reenforcing means and size, the two types of brushes, as illustrated, remain, in principle of construction, practically the same, and differ from all other makes of brushes, devised for like purposes, in simplicity of construction, there being no nailing of ferrule to a separate fiber, or other material, plate, nor the fastening to this plate of metal partitioning elements by screws or nails.

In the assemblage of parts and construction of my brush, a preferred .plan is to arrange the bristles, constituting the bristlebody, in the usual manner, placing the partitioning means at the butts, constituting one extremity of the bristle-body, and between successive 'layers of bristles, supplying this extremity of the bristle-body with the usual rubber preparation for vits rubber-set and subjecting this body to the necessary compression, after which the brush head holder, constituting the brush-back, is placed in position and secured therein by vulcanization. The handle, like all other parts, being standardized, is inserted in its prepared opening and secured (therein by means of a screw entering through the apex of a partitional member. To lend to strength of union between bristle-body and ferrule-bearing plate and give a locking effect therebetween, and inward flare is given to the brush head holder, resulting in giving to this member a frustum shape, and insuring for the individual bristles a proper direction and certainty of alignment.

Having thus described my invention, what `taining recess` and means for seourii'ig this I olairn and `desire to secure by LettersPatent is: .Y Y Y l. In Combination, a brush head comprising a plurality of separated rows of bristles,

Y a sooketed holderv in whichr said lbrush head is secured, said holder being,` provided with an opening in the base thereof, a reenforoing bead surrounding said opening, a handle,

alreenforoingferrule on said handlehaving aportion seated within the reenforoing bead n.on said holder, and means cooperating `With said brush head and saidhandle for Vholding the parts Vin assembled relation. Y
